I have a 77 f250 I was wondering if anyone knows if there is a way of getting rid of the power assist cylinder set up and putting on a power stering box?

 

I'm assuming you have a 4x4?

 

Search highboy steering there have been a few threads on this, Think u would use a 78 two wheel drive steering gear box.

 

yeah its a 4x4 thanks for the help so far

 

What's wrong with you power assist (laughs) the 78/79 p/s swap is a popular one, do a search and there's numerous detailed threads on this very topic.


As a side note: i'll take your old power assist if you want to part with it.

 

I look up the old threads noone had any pics of mods does anyone have any pics.


power assist cylinder is junk leaking and is in bad enough shape prob. wouldnt even be a good core

 

They can be rebuilt but are very expensive to do so, most guys just do the 78/79 p/s swap when it comes to that.

 

do u have to cut the off well i mean grind the weld

 

Montana highboy the truck I just bought came from montana not sure but it was used as wood hauler from the mountains

 

Yep, you need to cut the weld on the cylinder in order to rebuild it (not one of Fords best ideas).

 

where do you get the kit to rebuild it?

 

This is how I did mine. I used a gear box from a 78/79 F250 4x4 along with the drag link. A little fabrication work, but works pretty good. I ditched the stock steering rod and went a Borgeson steering rod that is adjustable and much better than stock. A few other things I had to do was notch out the radiator support a bit to clear the gearbox. The power steering pump pulley comes close to the gearbox, but works.

 

You do some great work there Buck.

I went a slightly different direction, and used a Saginaw box. Many boxes are, or have been used, and some are less desirable than others. Three bolt 1/2 ton 4x4 boxes have been used as have the 2wd boxes. Unfortunately the 2wd box has such a long sector, and has some funky angle it is just not a very good box for this upgrade. Another variable is crossover steering, and this 2wd box is just useless.

If fab skills are not up to cutting a frame / crossmember, you can add the three bolt box donated form a 78/9 F150 or full size Bronco right to theoutside of the frame, but this requires some sort of crossover steering or inverted "T" at a minimum.

Some pics of the Saginaw:
